Energizer 7W LED 2D 4-Pin Bulb GR10q - 4000K Cool White 750lm Non-Dimmable

The Energizer 7W LED 2D bulb is a direct replacement for older compact fluorescent 2D lamps, using a GR10q 4-pin base that fits into existing bulkhead fittings, recessed luminaires and 2D lamp holders without rewiring. The bulb produces 750 lumens at 4000K cool white, delivered through a broad flat profile that spreads light evenly across corridors, stairwells, storage areas and communal spaces.

Designed for utility and functional lighting rather than decorative use, the bulb runs significantly cooler than the CFL equivalent and draws just 7W on mains power. The 4000K colour temperature sits between neutral and cool white, providing clear visibility for task areas, garages, workshops, fire exits and service corridors without the warmer tones used in living spaces. Non-dimmable operation keeps the circuitry simple and the cost low.

The flat 2D form factor means the bulb sits close to the ceiling or wall when fitted into a bulkhead or recessed housing, maintaining a low profile in tight spaces. Energizer rates this LED version with a 30-year lifespan based on typical use patterns, significantly outlasting CFL 2D lamps that required periodic ballast maintenance. The energy rating of F reflects the trade-off between lumen output and wattage draw for this category of replacement LED.

What fittings does this bulb work with?

The GR10q 4-pin base fits into any bulkhead, recessed luminaire or lamp holder designed for 2D compact fluorescent lamps with the same base type. It replaces older CFL 2D lamps directly without needing to change the fitting or wiring.

Is this suitable for bathroom or outdoor use?

The bulb itself carries no IP rating. Whether it can be used in bathrooms or outdoors depends entirely on the IP rating of the fitting it's installed into. If the bulkhead or luminaire is rated IP44 or higher, the bulb can be used in damp or outdoor locations when enclosed.

What colour is 4000K cool white?

4000K sits between neutral and cool white. It's whiter and crisper than the warm yellowy tones of 2700K-3000K domestic lighting, but not as stark as daylight-equivalent 6000K+ LEDs. It suits utility spaces, offices, workshops and service areas where clarity matters more than ambient warmth.

How long does it last?

Energizer rates this LED 2D bulb with a 30-year lifespan based on average daily use patterns. Actual lifespan varies depending on how many hours per day the bulb is switched on, but it will significantly outlast CFL equivalents that typically lasted 8,000-10,000 hours.
